LibriVox

I have been scouring LibriVox for audio of books or stories by may favorite authors but have had very little luck.  The only author that I found on there that I would be interested in perhaps having an audio version was L. Frank Baum after searching for at least 10 others.

This leads to my question.  When can we legally make an audio version of a book?  What are the legalities behind these recordings.  Such as quite a few of the L. Frank Baum books are over 100 years old now, however books by Christopher Rice are less than 20 years old.  I would guess that due to copywrites the Christopher Rice book can not yet legally be put on a free audio version.

I am happy to see after doing quite a bit of searching, that there is actually a genre option.  Due to this option I can pick a genre that I am interested in and find options that I may never have picked before.  This way I could at least find something like the authors I was looking for.

I am relatively excited about this program and would love to read, even if just a short story for the site.
